Question

find the value of the line integal , when \(\large F(r)=|-y,-xy|=-yi-xyj\) and C is the circuler ac from A to B

Answer 1

A line integral of a vector function F(r) over a curve C:r(t) is defined by
\(\large \int_C F(r).dr=\int_a^b F(r(t)).r'(t)dt \)

\(\large r'=\frac{dr}{dt} \)

Answer 2

@ganeshie8 have an idea ?
